SPRING BED BOTTOM.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed December 12, 1905. Serial No. 291,402.

T0 at whom it may concern.-

Be it known that I, GEORGE A. MELLON, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Spring Bed-Bottoms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of spring bed-bottoms in which spiral springs are used and it has for its object to furnish a construction of bed-bottom that is of more rigid construction by the use of elevated subend rails and strain-Wires connected to said subend rails to relieve the main bed-bottom springs of strain, thereby increasing the life of said springs and making it possible to use a less number of such springs.

The invention also has for its object to provide, in connection with the strain-wires mentioned, tension-springs that permit play of the wires.

It also has for its object to provide connection between the strain-wires and'the mainsprings at opposite points at the ends of the springs, whereby the springs are permitted to partake of lateral movement while yieldingly held by the strain-wires, thus allowing the main springs to act with freedom, although restrained.

The invention also'has for its object to provide a construction whereby the mainsprings are rigidly held at their lower ends while yieldingly held at their upper ends.

The invention also has for its object to provide a construction that permits of the application of a mattress or pad to the bedbottom for the purpose of rendering it of box-like form and a speciallyconstructed mattress for use in producing the box-like shape of the bed-bottom.

Figure I is a top or plan view of a part of my bed-bottom. Fig. II is a side elevation of the parts illustrated in Fig. I. Fig. III is an inverted plan view of the parts illustrated in Figs. I and II. Fig. IV is an enlarged perspective view of one corner of the bed-bottom in upright position. Fig. V is an enlarged perspective view of fragments 'of one of the lower side rails, mainsprings, and longitudinal and transverse spring-supporting I wires. Fig. VI is a perspective view of my bed-bottom with the mattress shown applied thereto.

1 designates the side rails of my bed-bot- I tom and 2 designates the main or lower end rails, said rails being firmly united to each other by rivets or other suitable means of fastoning.

3 designates sub or upper end rails surmounting the main end rails and supported at an elevation above them by uprights or posts 4, secured to the end rails, and alsoby braces 5, having their ends secured to the side rails and the subend rails. The side rails and end rails are all preferably constructed of angle-b ars, and when made of bars of this kind each rail has a horizontal wing that extends inwardly from the outer sideof the rail. I

6 designates the mainsprings of the bedbottom, Which are preferably of the usual spiral or double-cone form.

7 designates longitudinal 9 designates transverse bottom-wires that extend from side to side of the bed-bottom at right angles to the longitudinal wires. The transverse bottom-wires extend through the kinks 8 of the longitudinal bottom-wires at each point at which said kinks are encountered and pass beneath the lower coils of the mainsprings engaged by said kinks, whereby the mainsprings are firmly held from movement due to interlocking engagement of the crossing bottom-wires with each other and the confinement of the lower coils of the mainsprings. The transverse bottom-wires are preferably secured to the side rails of the bed-bottom by passing their ends through perforations 1 in the side rails. (See Figs. III and IV.) These transverse wires may, however, be permitted to act yieldingly by the introductlon of coiled or other springs 10.

(see Fig. V,) connecting them to the side rails.-. The mainsprings of the bed-bottom,

bottom-wires that extend from end to end of the bed side and end rails and elevated subend rails for maint-aininga fixed elevatedpoint for the i which are seated uponthe longitudinal and transverse bottom wires for their support,

ing one end attached to a correspondingstra1n-w1re and its other end inserted through an aperture 3 in the subraill Each of the strain-wires 11 is connected to. the mainspring'6of the bed-bottom-that are disposed in line with the str-ain-wires, and this connection is made with respect to two rows of themainsprings, whereby those of one row are united to=the springs of'the next adja cent row through the medium of each independent-strain wire. The various strainwires are attached to the upper ends of the mainsprings at diametrically opposite points from each other in order that the strainwires will act in common with each other to resist lateral movement of the springs in eitherdirection transversely of the bed-bottom. The means I prefer to employ for the connection ofthe strain-wires to the mainsprings is metal olasps or tie-straps 13, which are bent around thestrain-wires and the'upper coils of" the mainsprings; but any other suitable means of attachment may be used.

1' is-a brace-bar, preferably of angle-iron, that extends transversely between the side rails 1' to connect said'rails and bracethem against spreading action.

Iwouldpoint out as advantageous features of" my bed-bottaom that by its construction, including the frame, consisting of the main support of the mainsprings in upright position and by combinatlon therewith of the tension-springs and longitudinalstrain-wires much of the strain otherwise received by the mainsprings is relieved, thereby increasing the life of such mainsprings. This construction also permits of a less number of mainsprings being used, as willlbe obvious.

Another feature of advantage is that gained by supporting the mainsprings at two opposit-e points by the top longitudinal strainwires and alternating the positions of the mainsprings in the various rows, sothat the longitudinal strain-wires in conjunction with the mainsprings, will serve to maintain all of the mainsprings inupright positions due to the alternating arrangement. Another ad'- vantage to which I would call attention is that secured by the provision of the tensionsprings uniting the top longitudinal strainwires to-the subend rails and the connection of said strain-wires to the mainsprings by the binding members 13. This construction permits freedom of movement of the mainsprings longitudinally of the bed-bottom due to the existence of' the tension-springs and freedom of movement of said mainsprings transversely of the bed bottom due to the hinge-like connection between the strainwiresand the mainspring.

I wish also to call attention to the advantage of the bottom construction of my bedbottom, which provides a rigid support for the mainsprings due to the connection of tlle longitudinal and transverse bottom strain- .wires which are interlaced with each other and'with the lower coils of the mainsprings.

In Fig. VI, I have shown my bed-bottom .withmy mattress l l-appliedthereto, thereby rendering the hed-bottomofbox.shape. This ,mattress has introduced into its side edges side rods 15 and intoits end edgesendrods ,16. Inthe sides of the mattress, which are 1, ada tedto ext'end'downwardly at the sides of :the lied-bottom, are-eyelets 17, that are lo- ;cated above the side rods'15. The side rods serve to hold the depending sides of the mat- ,itress in a straight condition throughout the lengths of the sides. The depending sides of ,the mattress are secured to the bed-bottom ,frame by lacingrstrings 1-8, that are threaded through-the eyelets 17 andextendfrom said ;eyelets to studs 1, projecting from the side rails of 'the bed-bottom, thereby furnishing a simple and efficient means forattachingthe ;mattress at. its sides and one that can be readily detached when the mattress is to be removed. The endrods 16 serve to hold the ,ends of the-mattress ina straight condition, and these-ends are attachedto the bed-bottom frame by hooks 19, which are loosely con.-

nect'ed'to the-end rods and are adapted to be moved'into engagement withthe subend rails.

I claim l 1. In a spring bed-bottom, the combination of a frame having elevated ends, mainsprings, means connected to said. frame for supporting said'mai'nsprings, andstrainewir-es connected directly to the elevated portions of" said frame and having loose connection with terminalcoils of said mainsprings, substantially as set forth.
